Stop using Dorzostill and contact your doctor immediately if you suspect that Dorzostill is causing an allergic reaction (for example, skin rash or itching).

Children

Dorzolamide has been studied in infants and children who have raised pressure in the eye(s) or have been diagnosed with glaucoma. For more information, talk to your doctor.

Elderly

Dorzolamide has been shown to have the same effects in elderly patients as in younger.

Using other medicines

Please tell your doctor if you recently have used, are using or plan to use any other medicines, including other eye drops or medicines obtained without a prescription, particularly if you are taking large doses of painkillers containing salicylic acid (e.g. aspirin). Although there is no evidence that Dorzostill interacts with painkillers containing salicylic acid , some other medicines which are related to Dorzostill and which are taken by mouth, have been known to interact with painkillers containing salicylic acid .

You should also tell your doctor if you are taking another carbonic anhydrase inhibitor such as acetazolamide.

Pregnancy and breast-feeding

Ask your doctor for advice before taking any medicine.

If you are pregnant or likely to be pregnant, you should not use Dorzostill.

These eye drops should not be used while breast-feeding.

Driving and using machines

No studies on the effects on the ability to drive and use machines have been performed. Possible side effects of Dorzostill such as dizziness and visual disturbances may affect your ability to drive or operate machinery. If you experience such side-effects, you should not drive or operate machinery.

Important information about some of the ingredients of Dorzostill

Dorzostill contains the preservative benzalkonium chloride, which may cause eye irritation. This preservative may be deposited in soft contact lenses and may possibly discolour the lenses. If you wear soft contact lenses, you should consult your doctor before using Dorzostill. It is important that your lenses are removed before using your eye drops and not put back into your eyes until 15 minutes after using your eye drops.

Hoe gebruikt u dit middel?

Always use Dorzostill exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure.

Dosage and frequency of administration

When Dorzostill is used alone, the usual dose is one drop in the affected eye(s) three times a day, for example in the morning, in the afternoon and in the evening.

If your doctor has recommended you use Dorzostill with a beta-blocker eye drop to lower eye pressure, then the usual dose is one drop of Dorzostill in the affected eye(s) two times a day, for example in the morning and in the evening.

If you are using Dorzostill with another eye drop, the drops should be instilled at least 10 minutes apart. Alternatively if you are going to use Dorzostill to replace another eye drop medicine, used to lower eye pressure, you should stop using the other medicine after taking the proper dosing on one day, and start Dorzostill on the next day.

Do not change the dosage of the drug without consulting your doctor and ask your doctor or pharmacist explain anything that you do not understand. If you must stop the treatment, contact your doctor immediately.

Instructions for use

Dorzostill is intended for ocular use.

Do not allow the tip of the container to touch your eye or areas around your eye. It may become contaminated with bacteria that can cause eye infections leading to serious damage of the eye, even loss of vision. To avoid possible contamination of the container, keep the tip of the container away from contact with any surface.

Always wash your hands before putting in your eye drops.

  1. To open the bottle unscrew the cap.
  2. Tilt your head back and pull your lower eyelid down slightly to form a pocket between your eyelid and your eye.
  3. Squeeze lightly the upturned dropper bottle until a single drop is dispensed into the eye. Do not touch the eye, eye lid or anything else with the dropper tip. Whilst keeping the affected eye closed, press your finger against the corner of the closed eye (the side where the eye meets the nose) and hold for 1 minute.
  4. Repeat steps 2 & 3 with the other eye if instructed to do so by your doctor.

Replace the cap immediately after use by screwing down until it is firmly touching the bottle. Do not over- tighten the cap.

The dispenser tip is designed to provide a pre-measured drop; therefore, do not enlarge the hole of the dispenser tip. After you have used all doses, there will be some Dorzostill left in the bottle. You should not be concerned since an extra amount of Dorzostill has been added and you will get the full amount of Dorzostill that your doctor prescribed. Do not attempt to remove the excess medicine from the bottle.

If you use more Dorzostill than you should

If you put too many drops in your eye or swallow any of the contents, you should contact your doctor immediately. Symptoms include sleepiness in case you have swallowed Dorzostill and nausea, dizziness, headache, tiredness, fatigue, abnormal dreams and difficulty in swallowing after application of too many drops in the eyes.

If you forget to use Dorzostill

It is important to take Dorzostill as prescribed by your doctor. If you miss a dose, take it as soon as possible. However, if it is almost time for the next dose, skip the missed dose and go back to your regular dosing schedule.

If you stop using Dorzostill

If you must stop treatment, contact your doctor immediately.

If you have any further questions on the use of this product, ask your doctor or pharmacist.
